Disk Image Utility

I am trying to create a disk image from a data CD. I am following the instructions provided under Help, but I get an error stating "Internal file system error."
Any ideas what's going on?
Here are the instructions I'm following:
To duplicate a CD or DVD:
Insert the CD or DVD disc in the optical drive, and select it in Disk Utility’s list of disks and volumes.
Choose File > New > “Disk Image from [name of disc].”
Type a name for the disk image.
Choose “compressed” or “read-only” from the Image Format pop-up menu.
Choose “compressed” to create a smaller disk image. Choose “read-only” to create a disk image that’s quicker to create and open.
Click Save.
After Disk Utility creates the disk image, eject the original CD or DVD.
Select the disk image in the list of disks and volumes, and choose Images > Burn.
When the Burn Disc dialog appears, insert a blank CD or DVD, and then click Burn.

Instead of “compressed” or “read-only”, try "CD/DVD Master".

I want to encrypt data using disk image - will the encryption be retained when the data is backed up by Time Machine?

I want to use the Disk Image utility to create secure, encrypted information storage on my Mac. I am using Time Capsule with Time Machine to back up my hard drive. Will the file still be encrypted on Time Capsule? I am concerned that if someone had access to Time Capsule they could get the data that I want to protect.

If you're not already, you should consider using a sparse bundle disk image as it is more compatible with Time Machine.
With a regular disk image, the image is a single file. If you make changes to the internal files, the entire image will have to be backed up. With a sparse bundle, the image is split into lots of small files. That way, only the small part that contained the changes will need to be backed up.
If the image is small, it doesn't matter much, but if the image is 50GB, you don't want to waste 50GB Of backup space for a 5KB change.

Disk Utility create encrypted disk image hangs

I'm trying really, really hard to backup my data but apple is not making it easy for me.
I need my files encrypted for an offline backup. Time machine only allows home folder to be encrypted, and due to my home folder being on my SSD drive I cannot fit my files all in there, not by a long shot.
Using Disk Utility, I choose "new disk image from folder", and select "read only", 256-bit encryption. Some of the folders worked. However some will just hang for hours on "Creating Image, copying...". I can see at the destination the dmg file has stopped incrementing larger. It has reached the full size of the folder approximately. Does apple fail at some file types? I already ran disk repair several times to no avail. I don't know what else to try, it just doesn't want to work. All I want is an encrypted backup, that any OSX install can retrieve without any special software involved. Sometimes I'll get a very unhelpful error message "Operation not supported". Whatever that is supposed to mean. Google was no help so hoping for some insights here.

Create an encrypted sparse disk image instead of from folder, mount it, and then drag & drop your files into ii.

Disk Utility doesn't finish creating new disk image - naming issue??

Recently I upgraded to Snow Leopard and carried along an empty disk image created in OS 10.4.11. I use these for archiving data on read-only DVDs and password protect the images.
In the earlier OS, I found the practical limit for the dmg was 4.3 GB, containing 4.27+ GB of data (anything larger failed when attempting to burn data DVDs). Today, when I looked at my empty dmg file, the OS 10.6.6 Finder showed it to be larger both inside and outside (just under 4.7 GB inside I think - didn't write it down). I suspected that it may be corrupted or at least not give correct directory information, so I deleted this dmg as a precaution and tried to make a new one with the old size by selecting custom size within Disk Utility. Now every time I try to create a new dmg this it stalls at about 100 MB.
The image format panel has several additional settings in OS 10.6 . There are two places for names - in the "Save as" field above and in the "Name" field below. (Haven't yet found any documentation where the reason for this is explained or which lists possible name limitations. The Help info appears to be identical to what was in 10.4) I've tried making both names the same, but it still stalls
Disk Utility settings:
Save as __Diskname
Name in lower field __Diskname (have also left it blank no difference)
Custom 4.3 GB
Mac OS Extended (journaled)
128 bit encryption
single partition
read/write format* (also tried CD/DVD master - no difference)
* All files are not necessarily added at once so I'm pretty sure I want this to be read/write

In case this isn't obvious I mean read/write formatting on the hard drive, but when burned the format will remain the same whether or not the disk used is rewritable

Hi Michael,
Did you reformat it HFS+ or something else?
Some USB2 Flash Drives Write at a disappointing USB1 speed, but Read at USB2 speeds.
From what I can find, that isn't one of them and should take maybe an hour & a half to transfer 30 GB to it. Of course if write speed IS USB1, then you could expect 2 days or more.
I'd stop it. Reformat it, then make the Image on the HD and try transferring it.

Unable to create an encrypted disk image with Disk Utility

Hi:
With our upgrade to Lion a few weeks ago, we're now unable to create an encrypted disk image of any type using Disk Utility any more. This problem occurs on 3 different machines, and is reproducible whether one is using an internal HD or an external FW HD. We can successfully create nonencrypted disk images.
This is a duplicate post with all the details here: https://discussions.apple.com/message/18469359#18469359
We haven't had any luck with a solution trying various permissions fixes as helpfully suggested by other readers in response to the error message # (-60008 error), so I'm hoping that someone else has run across a solution from the encrypted disk image perspective and that this tag line will generate some help.
Thank you!

Save As: 01 (on Desktop)
Name: 01
Size: 100 MB
Format: Mac OS Encrypted (Journaled)
Encryption: 256-bit AES
Partitions: Single partition- Apple Partition Map
Image Format: read/write disk image
At the password window that pops up I enter: 1234567890
This says password strength is "Weak"
All works fine
Then I repeated this using:

At the password window that pops up I enter: 1234567890 and when I start to enter the next "1" I get the "Unable to create "02.dmg." (error -60008)

Disk Utility taking long time to open directory with disk images

Hi and thanks in advance.
I have a couple of CD and DVD disk images stored in a folder (and organized into several sub-folders) on a FAT32 volume.
The problem is that recently, Disk Utility takes forever to display the content of any of these folders when I select Open Disk Image from the File menu. The Select an Image to Attach dialog remains empty and the beach ball spins. After a very long time (10-15minutes? I've never had the patience to time it.), the contents will display, if at all. During this period of virtual inactivity, the program is unresponsive.
Since the FAT32 volume is also accessible from my Bootcamped Windows XP OS, I tried doing a disk check and a defragment but it hasn't improved my problem.
Any ideas?

HI,
Make sure your MacBookPro has sufficient free disk space to read the disk images.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 10% to 15% free disk space at all times.

Unable to create restore disk image with Disk Utility

I've tried three times in order to create a restore image of the users' volume of my Powerbook. I followed exactly the procedure explained typing "man asr" in a terminal window. I booted the Powerbook in target disk mode while connected to my iMac G5 from which Disk utility was run. Every time the disk image creation failed with a log report like this:
Creating Image HOME_HD.dmg
Initializing...
Copying...
/Volumes/HOME_HD: Authentication error
Initializing...
Finishing...
Initializing...
Creating...
Copying...
could not access /Volumes/HOME_HD/./Users/delos/Music/iTunes/iTunes Music/David Bowie/The Best Of David Bowie 1974-1979/01 Sound And Vision.m4a - Input/output error
Finishing...
Unable to create HOME_HD - Input/output error.
I don't know how my imported music could create such a problem to Disk utility, nevertheless I removed the incriminated song from the Music library but another one raised to be not accessible. Then I booted the powerbook from the supplied Tiger DVD too, and I got an error over the music file, something about an allocation that was 190 instead of 1, I got the volume repaired from Disk utility but the Disk image creation failed again without any hint because booting from DVD does not allow to save log file anywhere. Why on Earth I can't manage such a critical task as back up under Tiger while using Panther everything worked like a charm following the same procedure? Is anyone experiencing something similar?
Greetings
Gianmarco

Hi Lee, thank you for your answer, indeed I've just read carefully your article few hours ago, while I googled the net to find some hints on my issue. I think that I've followed exactly the right procedure to make the back up image, and can't find what is wrong. Actually Disk utility Repair disk successfully repaired the allocation bit (whatever that means) of the music files but that wasn't enough to let the creation of the disk image. Quite odd that the music files where recognized as messed up by Disk utility only booting from Tiger DVD and not while the Powerbook was connected to an iMac running Tiger too.
I'll do further investigation during weekend.
Greetings
Gianmarco

Trouble creating a small disk image with Disk Utility

When I try to create a disk image using Disk Utility the size option for 2.5MB is grayed out and I cannot override this by manually entering the size I want. Ideally, I would like to create a 500KB-1MB size image to store 1 or 2 files that I want encrypted. Thanks for any help.

Choose a filesystem which isn't journaled to get the 5MB option; if you want to create a 2.5MB image, specify Mac OS Standard or MS-DOS. Some disk formats have a minimum size.

Disk Images will not mount and Disk Utility will not runru

I am having some major problems with Disk Utility, Disk Images, and software update. First, Disk utility will not open or run. When I double-click the application icon, nothing happens, no message, nothing. I am running OSX 10.4.11. I have deleted diskutility prefs. I am able to run Disk Utility from the Startup DVD of Tiger. On first run, it verified and repaired permissions. I run verify and repair permissions several more times from Startup DVD and everything is fine. But Disk Utility on my startup HD will not work. Similary, NONE of my disk images will mount. No matter what Disk Image i try to mount, nothing will. And I cannot use Disk utility to mount them! So, no matter what I download, no images will mount. And thirdly, when I try to run software update, it will not work. I do get a message: it says, "Could not load Software Update." Finally, i tried to download Onyx to delete log files, etc.. but again, the disk image will not mount. I was able to install a dashboard widget called "maintidget" and was successful in running the daily, weekly, and monthly maintenance tasks. Can anyone help? Everything else works fine!!! All apps! Safari, Mail, iTunes, MS Office, everything works fine. Thanks for ANY help!

Previously, I had run verify permissions, repair permissions multiple times(from startup DVD) - no probems found. Deleted disk utility prefs. Run the maintenance taskes (daily, weekly, monthly). Nothing worked. But, I forget to check the drive for problems. So I ran disk scan. It found "invalid node" and repair disk could not do it. So, do I erase and do a fresh install or get DiskWarrior? I am running Leopard so I do not have Time Machine but I have backed up my documents, iTunes Library, iPhoto Library, etc... Another thing I found out the hardway is to sync all your bookmarks, mail settings and messages, etc... with .mac if you have an account. Any more suggetions?

Disk Utility reports "resource busy" and can't create an disk image

HI,
Just succesfully updated to Mountain Lion on my MBA and iMac. No problems. A very smooth proces.
But, on my iMac the Disk Utility are not able to create new images at all! I'm not sure if this relates directly to the update, as
DU works fine on the MBA.
I have tried to create a simple disk image from a folder, sparse bundle disk images and sparse disk images - with and without encryption.
They al gave this output from DU: "Unable to create "MYDiskImage.sparsebundle." (Resource busy).
I understand from other postings on the web that others have experienced the same message from time to time, but have not seen a fix for it anywhere.
I can see the "disk iamge" in the DU window (left pane) but are not able to locate it with Finder or on the computer anywhere, but are even able to "repair the
disk image with DU, but then there is actually no disk image when trying to locate it. Very strange.
Any help?
The DU log has this info:

Hi Darth,
Thanks for the suggestion. Somehow I managed to solve the issue (the question was posted in July), I think I restarted the computer a couple of times, but it's interesting that you mention Drive Genius and Drive Pulse, as I also had that app running!
Maybe Drive Pulse was also turned of here in my process and helped to solve the issue.
Anyhow, thanks.

Disk Utility won't finish creating a 30Gb encrypted disk image

How long should it take Disk Utility to create a 30Gb encrypted read/write disk image on a 32Gb Kingston USB 2.0 flash drive?
Once I started the process the dialog box said "Creating Image 'backup.dmg' [thermometer bar] Creating...". The bar took about an hour to fill up completely. Then the filled bar went completely empty and the bar is completely moving candystripes as though it's made no progress at all. It's been like that for hours. Should I give it another few days or is this never gonna work?

Hi Michael,
Did you reformat it HFS+ or something else?
Some USB2 Flash Drives Write at a disappointing USB1 speed, but Read at USB2 speeds.
From what I can find, that isn't one of them and should take maybe an hour & a half to transfer 30 GB to it. Of course if write speed IS USB1, then you could expect 2 days or more.
I'd stop it. Reformat it, then make the Image on the HD and try transferring it.

Disk Utility Hangs "Closing Session" when attempting to burn a disk image

I have been trying to burn a DVD of a disk image created with Disk Utility and the process repeatedly gets hung up on "Closing session". I have let it go for 15 hours (I assume that is long enough) before force quitting DU. Additionally, the drive is completely unresponsive until a complete reboot is made.
I have searched the discussions but can't find the same problem addressed elsewhere. Does anyonw have any suggestions?
Thank you.
PMG5 - Dual 2GHz Mac OS X (10.4.3)

Hi Marc,
Did you got any reply on this issue as I have exactly the same problem.
I actually broke up after 12 hours for 13GB to image.

Disk Utility Error 61 when attempting to create disk image on external driv

I would like to make occasional archive backups of my three macintosh computers. I bought a new Western Digital 2TB drive for this purpose, and formatted it as Mac OS Extended. Trying to do a disk image backup using Disk Utility, I follow the directions:
- Startup from an install DVD.
- Start Disk Utilities and select "Restore"
- Drag "Macintosh HD" into the Source box
- Click on "New Image" and select compressed and 128-bit AES encryption
This leads to the error message: Unable to create "....." (error -61)
I have enocountered this problem both with my iMac G5 and a MacBook, both running Leopard.
Does anyone know what this error means, what I am doing wrong, and/or if there is another way to create disk image backups? Help!

1. For reasons I don't know disc images seem to become more fragile the larger they get. They also can be subject to file corruption that affects the entire disc image, whereas file corruption on a clone would only affect certain files.
2. You cannot put multiple clones on the same volume. Each clone must be on a separate volume, but you can have multiple volumes on a single drive simply by partitioning the drive accordingly. Of course you need a drive large enough to accommodate each clone. Each clone should be to a space equal to the capacity of the cloned drive.
3. I'm not a big fan of TM, although I must confess it has become more reliable since it's release, especially with Snow Leopard. However, there are many backup utilities that can create clones, perform incremental updates, and archive changed files. See the following:

Disk Utility 'Disk Image from Folder' looses file create date?

Hi,
I have been working on creating backups that maintain the files' create dates. I have found the following anomoly using Disk Utility.
If I create a Disk Image From Folder, the create dates of all files are changed to be the same as the last modify dates. Not what I want.
If I creat a Blank Disk Image, and then using Finder to copy the files to the Disk Image, the create dates remain unchanged.
I can then burn the backup CD's with the Disk Image and the files' create dates are maintained. So, future restore from the backup CD will contain the original files' create dates.
Does anyone know if Disk Utility's Create Disk Image from Folder is supposed to loose the files' create dates? What other file attributes are being lost? Mac OS X maintains all of these attributes, and create dates via Finder copies, I would expect the Disk Utility Create Disk Image from Folder to do the same.
Bob Horton

To follow up on this post, I know at least part of the answer. The difference between the two becomes clearer if you read the documentation (man pages) for hdiutil and asr. Image 1 will be created in file mode, whereas image 2 will be in block mode, ie bypassing the file system. Image 1 will consist of a series of files, whereas image 2 will contain a series of blocks, mirroring the original layout of the hard disk.
Technically the latter should be faster to restore (in block mode), although Apple recommend the first procedure (see man page for hdiutil). I haven't seen any evidence that images created in block mode can be mounted or restored, although you might be able to burn such images to a optical disks if applicable.
As I've pointed out in another thread (http://discussions.apple.com/thread.jspa?threadID=1508199&tstart=0) I believe that this functionality should not be offered in disk utility, and I consider it a serious bug.

Disk Utility fails to create encrypted disk image

When creating a disk image using 256 bit encryption and a purely numeric password longer than 13 characters the following message appears:
Unable to create "ABC.dmg." (error -60008)
the error happens upon typing the 14th consecutive number into the Password field. I have created images under the same conditions in the past, Not sure if this is caused by Lion.

Looks like one of the drives is bad.
While it passed being zeored with Disk Utility, it failed about 15 minutes into a 'Certify' using SoftRAID.
Now waiting on a replacement drive from Newegg.
